One e-cigarette with nicotine leads to adrenaline changes in nonsmokers' hearts


Electronic cigarettes have been touted as both a safer alternative for smokers and as an effective way for people to gradually quit smoking altogether. But a new study shows that nicotine inhaled from e-cigarettes can greatly increase a person’s heart rate and aggravate the sympathetic nervous system.

Repairing damaged hearts with self-healing heart cells


New research has discovered a potential means to trigger damaged heart cells to self-heal. The discovery could lead to groundbreaking forms of treatment for heart diseases. For the first time, researchers have identified a long non-coding ribonucleic acid (ncRNA) that regulates genes controlling the ability of heart cells to undergo repair or regeneration. This novel RNA, called ‘Singheart,’ may be targeted for treating heart failure in the future.

Understanding how fish grow their hearts could help humans, professor finds


A protein that enables fish to change the size of their hearts based on the temperature of the water has now been identified by researchers. Understanding how fish are able to naturally add and remove collagen could lead to the development of treatment modalities for humans that enables a more controlled way for the heart to repair itself after a heart attack.
